From ancient essences such as Frankincense, Galbanum, Myrrh and Sandalwood to relatively uncommon oils like Gaiac Wood and Cypress (Blue) from Australia, Spruce (Red) from Canada, and Neroli (Orange Blossom) from France or Egypt, Wisdom of the Earth offers a wide range of species and prices. Our essences are offered primarily in the 15 ml (approx. 450 drops) size, with some offered in both a 15 and a 5 ml (approx. 150 drops) size, and the more costly or rare essences in only a 5 or 2ml size. Larger quantities can be poured by request, supplies permitting.
